ABSTRACT
Some promising recent schemes for XML access control em-
ploy encryption for implementing security policies on pub-
lished data, avoiding data duplication. In this paper we
study one such scheme, due to Miklau and Suciu. That
scheme was introduced with some intuitive explanations and
goals, but without precise definitions and guarantees for the
use of cryptography (specifically, symmetric encryption and
secret sharing). We bridge this gap in the present work. We
